I will often run this command to make sure all my docker containers are stopped and removed before running docker-compose up. Sometimes when you restart your system, old containers will start back up automatically in the background.

docker stop $(docker ps -aq) && docker rm $(docker ps -aq)

Here's an ecto changeset validation for urls:

  @doc """
  validates field is a valid url

  ## Examples
    iex> Ecto.Changeset.cast(%ZB.Account{}, %{"website" => "https://www.zipbooks.com"}, [:website])
    ...> |> Utils.Changeset.validate_url(:website)
    ...> |> Map.get(:valid?)

I have this abstraction in my application code called a "CloudFile". This is where I store in the database information about files on S3 and it gives me a resource for other resources to own. For example, a user would have an avatar_cloud_file_id. On the front-end, I would load this relationship and display the avatar with user.avatar_cloud_file.download_url

defmodule RL.CloudFile do
  use Ecto.Schema
  import Ecto.Changeset
